IAI SPECIAL EDITION: Validity and reliability of the Indonesian version of the Self-Efficacy for Appropriate Medication use Scale (SEAMS-I)
Keywords:Medication Adherence, Reliability, Self-efficacy, Stroke, Validity
Background: A keystone to achieving successful therapy is medication adherence, supported by the patient’s self-efficacy on using medication. In Indonesia, the development of quality instruments to measure patient adherence based on self-efficacy remains limited.
Objective: This study aimed to evaluate the validity and reliability of the Indonesian version of the Self-Efficacy for Appropriate Medication use Scale (SEAMS-I) in patients with stroke.
Methods: After forward and backward translations, a cross-sectional survey was conducted among ambulatory patients with stroke attending a neurology clinic of a public hospital in Jember, East Java, Indonesia, to evaluate the instrument’s structural validity and reliability using convenience sampling.
Results: A total of 114 participants (62, 54.4% males) signed the informed consent, and exploratory factor analysis was performed on the 12-item SEAMS-I. The Kaiser-Meyer-Olkin measure of sampling adequacy was 0.815, with a significant Bartlett’s sphericity test p < 0.001 and a Cronbach’s alpha value of 0.851.
Conclusion: The SEAMS-I demonstrated good structural validity and reliability when tested in patients with stroke.
